After more than two years of hard work, researchers at the Industrial Technology Research Institute of Wuhan University have finally successfully developed environmentally friendly waterborne varnish technology in October 2003. Water-soluble coating oil is a new type of printing glazing material that has been researched and developed by developed countries in recent years. Because of its environment-friendly and high-performance features, it is favored and valued by the printing industry.
The product has been accepted as a patent for invention by the national patent department and won the gold medal of China Patent Technology Exposition. After being used by several units, the general response is good. It is understood that this product is colorless, odorless, non-irritating, non-organic volatiles, strong transparency, high strength, good abrasion resistance, scratch resistance, no influence on the color of printed materials, bright printed material, and not yellowing. After drying, it does not fade, and the product quality is stable, the cost is low, the source of the material is wide, and the use of transportation is convenient. It is not comparable to Other solvent-based coatings.
According to statistics, China currently has more than 50,000 packaging and printing companies with an annual output value of over 30 billion yuan, which is an important part of the national economy. China's printing and packaging industry will print about 20,000 tons of coating oil every year during the “10th Five-Year Plan†period, and will increase at an annual rate of 15% to 20%. The development of this product has broad market prospects. There is no "three wastes" for the production of the product, and the domestic availability of raw materials.
